I 1.1 Location and Access The project area is located within NTS mapsheet 43B/12 which is located in the central James Bay Lowlands of northeastern Ontario (Figure 1). The location of the Logan kimberlite relative to De Beers Canada Inc's 100% owned Victor Mine is shown in Figure I 2. The Victor Project area is located approximately 90 kilometres west of the First Nations I community of Attawapiskat. No year-round road access exists in the area. The Victor Mine is located 350 km from the nearest all-weather road and is only accessible year round by fixed-wing aircraft landing on a 1,000 m long gravel airstrip located aC\jacent to the mine I site. Fuel, heavy equipment and bulk materials are delivered to site each winter via a 240 km I long ice road which links Moose Factory and the community of Attawapiskat. A temporary 110 km long winter road links Attawapiskat and the Victor mine site. In its development of the Victor Project, De Beers is committed to sustainable I development in local communities within northern Ontario and is signatory to four separate community agreements: I - an impact benefit agreement (IBA) with the Attawapiskat First Nation (November 2005), - a working relationship agreement with the Taykwa Tagamou First Nation (May 2005), - an IBA with Moose Cree First Nation (September 2008) and I - an IBA with Kashechewan and Fort Albany First Nation (February 2009) I 1.2 Dispositions and Ownership Currently, De Beers Canada Inc. holds 80 claims and 16 mining leases in the greater Victor Project area. All of these claims occur in the Porcupine Mining Division of I northeastern Ontario. Upwards of 179 additional claims held by competitors surround De Beers' landholdings in the area. I As shown in Figure 3, the Logan kimberlite situated in mineral permit 4242476 is enclosed by four contiguous claims. The relative sizes and associated annual assessment requirements on claims in the Logan target area are listed in Table 1. I All of the claims are 100% owned by De Beers Canada Inc.

I Towards the north, the Hudson Bay Lowlands are broken by a broad rise, some 160 km long and 80 km wide that is roughly outlined by the 120 m contour that lies aside Cape Henrietta Maria Arch which presents a broad, subdued promontory that stretches inland I from Cape Henrietta Maria to the southwest corner of the lowlands (Figure 5) (Thorleifson et aI., 1993). The major axis of the rise and its highest point consists of an inlier of Proterozoic and Precambrian rocks which form an imposing cuesta, up to 150 m in height that crosses Cape Henrietta Maria Arch at right angles in the vicinity of Sutton and Hawley I Lakes (Bostock, 1976). Surficial materials throughout the James Bay and Hudson Bay Lowlands are dominated by I till, marine deposits and peat (Sado and Carswell, 1987). Surface glacial lineations oriented parallel to the former glacial ice flow direction as mapped by Prest et a/. (1968) indicate a pronounced southwest-northeast direction in the Severn River basin and a I pattern of converging southward flow in the Winisk River drainage further towards the southeast. I Major rivers of the Hudson Bay Lowlands include the Harricanaw, Moose, Albany and Attawapiskat which flow into James Bay, and the Winisk, Severn, Hayes, Nelson and Churchill rivers which flow into Hudson Bay (Cummings, 1968). The source of these low I gradient rivers is mainly in Precambrian higher ground bordering the lowlands. The main drainage pattern in the central Hudson Bay Lowlands is roughly controlled by the Cape Henrietta Maria Arch which forms an irregular divide between streams flowing I northward into Hudson Bay and those flowing eastward to James Bay (BostOCk, 1968). The present day drainage pattern further reflects the presence of the two large basinal features: the Moose River Basin in the south, and the larger Hudson Bay Basin to the I north (Figure 5). Rivers whose outlet is Hudson Bay show a large scale radial drainage pattern, whereas rivers which drain into James Bay have become adjusted to structures in the underlying sedimentary rock sequence (Cumming, 1968). Most lakes in the area have I little accompanying valley and many are shallow (Bostock, 1968). The Victor project area straddles the Attawapiskat River whose drainage basin comprises I an area of about 49,000 km 2 which extends for 670 km in a westerly direction from James De Beers Canada Inc. 2010 Assessment Report Diamond Dnlling Investigation of the Logan I(jmberlite I 4 I I I Bay (Figure 5). In it lowermost 400 km, the channel of the Attawapiskat drops only 183 m at a uniform rate of 0.4-0.6 m/km (Cumming, 1968). From the junction with the Muketei River, the Attawapiskat follows a slightly south of east course for 240 km to James Bay I where the river angles across reefal limestones of the Attawapiskat Formation. 1.4 Climate and Vegetation I The Victor Project area is characterized by a humid microthermal arctic climate (Koppen classification: Oct) (Martini, 1989). Summers are cool and four to five months long, with maximum precipitation occurring during the period July through September. Winters are I very cold and snowy. The region lies exposed to outbreaks of cold air from the arctic regions during all seasons and to occasional incursions of warm air from the south in the summer. The lack of major topographic features in the region means that local climates I are dependant of variations in terrain, vegetation and drainage. In winter, the movement of weather systems over the Hudson Bay Lowlands is related to I the dominance of a low pressure vortex situated over the northern half of Baffin Island.
